The price of elastomer modified asphalt waterproofing membrane can be said that any waterproofing membrane coated with an adhesive layer can have self-adhesiveness. The physical properties of this type of material are consistent with the original body, but the construction process becomes self-adhesive. The self-adhesive adhesive can be bituminous, acrylic, butyl rubber or other adhesives, which are a bit like adhesive tapes and pressure-sensitive tapes. The self-adhesive waterproofing membrane previously only refers to the self-adhesive waterproofing membrane of the body. In addition to the change of the construction process, it is very important that the self-adhesive membrane has creepage, which solves the problem of the membrane cracking in the base layer. Tension generates internal stress, which accelerates the aging and destruction of waterproofing membranes under stress. Another type of self-adhesive membrane is a waterproof membrane with a self-adhesive layer.
Cold bonding method: Use a rubber squeegee to evenly apply the special adhesive for polymer modified asphalt on the surface of the base layer. Then, while laying the coil, use a rubber roller to push the coil while venting the air until it is compacted. When the environment is stable and lower than 15℃, hot melt method should be used to treat the tower junction and coil winding head. Lap joint treatment: when the long-side tower is connected, the width of the single-layer waterproof tower is 100mm, the double-layer waterproof ge, 80mm, when the short-side tower is connected, the single layer should be ge, 150mm, and the double-layer should be ge, 100mm.

The price of elastomer modified bitumen waterproofing membranes should be uniform in strength when coating the waterproof layer, especially the joints, the male and female corners and the nozzle parts. Before painting and after painting twice, keep the perpendicular intersection angle, brush fully in place, the coating layer is thin, pay attention to the thickness at the nozzle and the corner of the pipe, do not exceed 1mm, so as to avoid dry cracking. After hours, perform sprinkling and maintenance. Do not damage the waterproof layer before condensing the water. Do not step on the water. You must also pay attention to the installation of sanitary ware. After completing the water storage test, the closed water level should be as high as possible, and the low water level should not be less than 20cm.
Commonly used indicators such as aging resistance and heat aging retention rate. Sbs waterproof membrane construction precautions. , the waterproof base surface (leveling layer) must be hard, flat, dry (the moisture content should not be greater than 10%) and clean, and there should be no anti-sand and various sharp objects. , if there is snow on the work surface, construction is not allowed when there is water and frost. , the coiled material should not be constructed under negative temperature conditions. If construction must be performed under negative temperature, measures should be taken to ensure that the waterproof layer after laying is free from cracks and poor adhesion.
Measures to deal with common problems. Bubble, hollow. Because the base layer is wet, the leveling layer is not dry, and the moisture content is too high, which makes the coating film hollow and forms blisters. Treatment method: first cut off all the bulging parts, expose the base layer, and drain the moisture. After the base layer is dry, repair it according to the construction method of the waterproof layer. Warped edge: The end or the end of the waterproof layer has peeled off from the base layer. The main reason is that the base layer has not been treated well, is not clean or dry, and the sealing process is not good when the head is closed. In the yin and yang corners, detailed nodes and other parts with relatively weak waterproofness, the waterproof strengthening treatment shall be carried out according to the design requirements to achieve the waterproof ability of the normal parts. According to the actual situation of the base layer, arrange the order and direction of the self-adhesive waterproof membrane paving. In order to make the positioning of the self-adhesive waterproof membrane more accurate and the effect of the paving more beautiful, it is necessary to play the baseline according to the width requirements in the specification. After the previous preparations are done, the self-adhesive waterproof membrane can be laid immediately.
The bending direction of the steel waterstop is specified, and it is set according to the water surface. Generally, the bend of the water stop plate of the basement wall is to the outside. Whether it is a horizontal steel plate waterstop or a vertical steel plate waterstop, it is necessary to make the installation direction of the two curved surfaces facing the water facing surface. Suitable for expansion and contraction deformation joints should not be installed or less installed. Induction joints can be selected according to different engineering structure types and engineering geological conditions, and water-stop measures such as lifting water-stop belt and post-pouring belt can be selected. The allowable settlement difference of deformation joints suitable for settlement cannot be greater than 30mm. When the settlement value is greater than 30mm, measures should be taken in the design.
Self-adhesive coiled material company self-adhesive coiled material, Yuexu Building Material, Shandong Yuexu Building Material is a comprehensive thermal insulation and waterproof material enterprise integrating production, sales and engineering. Main SBS waterproofing membrane, self-adhesive waterproofing membrane, closed-cell foam board, geotextile, neoprene, extruded board, polystyrene board and various new thermal insulation and waterproof materials. Key points of exterior wall insulation construction. Grassroots cleanup. Clean up the remaining floating ash on the concrete wall, release agent oil stains and other debris and plaster hollow parts, etc., and repair them. Asphalt waterproofing membrane. This kind of waterproof membrane can be divided into four types according to the material of the base tire used in its production, namely petroleum asphalt paper linoleum, petroleum asphalt glass cloth linoleum, petroleum asphalt glass fiber linoleum and aluminum foil surface linoleum. Among them, paper-based waterproofing membranes have now been banned from production and use. Modified bitumen waterproofing membrane. This kind of coiled material has relatively low temperature requirements during construction, and there are many options for the thickness of the coiled material, and the waterproof performance is quite reliable. Generally, it will not affect its waterproof effect after 20 years of use.
